Problems solved by technology

In certain applications, however, the luminaire needs to be assembled in the case of a high space at a short distance from the ceiling or at a great distance from the ceiling, which on the one hand leads to undesired heights on the ceiling side. Luminous density, which would be detrimental to the installation of such luminaires and thus limit the operational possibilities, or on the other hand would result in too low a luminous density on the ceiling side at large suspension heights and would be desirable in the space The proportion of indirect light becomes too small

Embodiment Construction

[0029]The main part of the luminaire, denoted as a whole by the reference numeral 1, comprises a housing 2 which, on its emitting side, ie on its side facing the space 3 to be illuminated, has a first light emitting area 4, which In the luminaire 1 of the exemplary embodiment, a light emission region extends substantially over the entire side of the housing 2 facing the space 3 , thus preferably extending in the emission surface E1 .

[0030] The housing 2 encloses a housing interior 5 by means of its light-transmitting bottom wall 2a on the emission side, the opposite side wall 2b, and a rear wall 2c opposite the first emission area 4, in which housing interior space 5 is enclosed by a not shown At least one connection means 6 for at least one lamp 7 , whose outgoing wires are connected to a power source, is provided and fastened eg to the inner wall of the housing. The lamp 7 can be, for example, a so-called fluorescent lamp, associated with its power supply is an operating ...

Abstract

The light (1) has a housing (2), and a light emission region (4) with a light influencing element (9) provided at one side of the light. Another light emission region (21) with another light influencing element (22) is provided at another side of the light for direct lighting. The another light influencing element is adjustable in two different positions (S1,S2).

Description

technical field [0001] The invention relates to a luminaire according to the preamble of claim 1 . Background technique [0002] In the case of luminaires of this type, the luminaires are of known design, in particular previously known as pendant luminaires. An important feature of this luminaire is that it has a first light-emitting area on one side of its housing for direct illumination of the space, and a first light-emitting area for indirect illumination of the space arranged on the luminaire in conjunction with the first light-emitting area. A second light emitting area on the opposite rear side of the area. The purpose of the second light-emitting area with the light-transmissive light-influencing element is to illuminate the surroundings of the luminaire at the sides and / or the rear to reduce the light intensity between the first light-emitting area and the surroundings of the luminaire difference, and / or in particular at the rear of the luminaire to generate indir...
